Characterization of peripheral nerve sheath tumors with 3T proton MR spectroscopy.
BACKGROUND AND PURPOSE The characterization of peripheral nerve sheath tumors is challenging. The purpose here was to investigate the diagnostic value of quantitative proton MR spectroscopy at 3T for the characterization of peripheral nerve sheath tumors as benign or malignant, compared with PET. MATERIALS AND METHODS Twenty participants with 24 peripheral nerve sheath tumors underwent MR spe...
متن کاملMalignant Peripheral Nerve Sheath Tumors (MPNST)
INTRODUCTION Malignant peripheral nerve sheath tumors (MPNSTs) are sarcomas which originate from peripheral nerves or from cells associated with the nerve sheath, such as Schwann cells, perineural cells, or fibroblasts. Because MPNSTs can arise from multiple cell types, the overall appearance can vary greatly from one case to the next. This can make diagnosis and classification somewhat difficu...
متن کاملHybrid peripheral nerve sheath tumors: A review.
Hybrid peripheral nerve sheath tumors (HPNST) are relatively recently described tumors. With ongoing research, a considerable amount of important findings have been made, much of which has substantial clinical implications. However, a comprehensive review of the whole topic has not been published in the literature so far. In the presented manuscript, the various hybrid tumors are discussed sepa...
متن کاملProton MR spectroscopy of pediatric cerebellar tumors.
PURPOSE To investigate the role of proton MR spectroscopy in pediatric cerebellar tumor diagnosis. METHODS Single voxel pulse sequences with long echo time (135 or 270 milliseconds, voxel size 8 to 19 cm3), were used to obtain proton spectra of primary pediatric cerebellar tumors. Eleven primitive neuroectodermal tumors (patient age, 2 to 12 years; mean, 7 years), 11 low-grade astrocytomas (a...
متن کاملQuantitative Proton Single-Voxel MR Spectroscopy in Malignant Breast Tumors at 3T: a Preliminary Study
Figure 1 shows the MR and MRS measurement of a patient with invasive ductal carcinoma. A: On pre-contrast images one lesion showed very dark intensity signal with irregular shape in a centered sagittal slice. The spectroscopic voxel (size, 1.6 × 1.6 × 1.6 cm) is superimposed on the hypointense lesion in the pre-contrast sagittal image. B: The MR spectrum was measured from the selected lesion. T...
